JOHN J ONES AND ALEXANDER GILLIES, OF TORONTO, CANADA.

STREET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 471,642, dated March29, 1892.

Application filed April 22, 1891- Serial No. 389,941- (No model.)

To all whom it may concern.-

Be it known that we, JOHN JONES, street commissioner, of the city ofToronto, in the county of York, in the Province of Ontario, Canada, andALEXANDER GILLIEs, blacksmith, of the same place, have invented acertain new and useful Improvement in Street- Sweepers, of which thefollowing is a specification.

The object of the invention is to construct a street-sweeper which canbe readily adj usted and which will be both substantial and easilyoperated; and it consists in the arrangement and construction of theparts hereinafter more particularly explained and then definitelyclaimed. v

Figure 1 is a perspective view of our improved sweeper. Fig. 2 is aperspective longitudinally-sectional detail of the broom used inconnection with our sweeper. Fig. 3 is, a perspective end view of thebroom, showing its operating mechanism. Fig. 4B is an inside view of oneof the end pieces of the broom.

In the drawings, A represents the platform or main frame of the machine,which is suitably supported at its rear end by the groundwheels B and atits front end by an ordinary wagon-truck, which we have not shown in thedrawings as there is nothing peculiar in its construction.

0 isa sprocket-wheel fixed to the wheel B.

D is a bar pivoted on the end of the wheelaxle E, which axle isstationary. 'A journalbox F is fixed to the opposite end of the bar D toreceive a spindle projecting from the yoke G. A bracket H is pivoted onthe bolts 1, which secure it to the yoke G, as indicated. The rear endof the bracket H has a rod J pivoted upon and arranged to support it, ashereinafter described.

K is a brace extending from the end ofthe bar D to the axle E, on whichaxle the said brace K is pivoted.

L is a sprocket-wheel, loosely journaled on a spindle M, extending fromand supported j by the bracket H. This sprocket-wheel L' is connected tothe sprocket-wheel C by the sprocket-chainN, so'that when thesprocketwheel 0 revolves with its Wheel B the motion of the said wheelis conveyed to the sprocketwheel L. The bevel-pinion O is cast upon orconnected to the sprocket-wheel L and is designed to mesh with thebevel-pinion P, fixed to the shaft Q of the brush R, the said shaft Qbeing suitably journaled at one end in the bracket H and at its'otherend in a socket 8, attached to the arm T, pivoted on a suitable supportU, fixed to the-platform A. A rodV is pivoted on the top of the socket Sand ex tends up to the bar'W. The bar W is pivoted on a bracket X,located substantially'in the center of the platform A. The bar Y, towhich the rod J is connected, is also pivoted on the bracket X.

Z is an equalizing-bar suspended on the end of the lever a, which issuitably pivoted, as indicated, and extends past the drivers seat b, asshown. This equalizing-bar is connected by the links (1 to thebar W andto the bar Y. As the rod J connects the bracket 1-1 (in which the shaftQ is journaled) to the bar Y, and the opposite end of the shaft Q issupported by the rod V, connected to the bar W, andas the equalizing-barZ supports both of the pivoted bars W and Y it follows that the shaft Qis carried by the bar Z, suspended from the end of the lever a. As theend of the shaft Q on which the driving-gearing is supported is heavierthan the opposite end of the said shaft, the link which connects the barY to the equalizing-bar Z is placed nearer to the outer end of the barYthan the link which connects the said equalizing-bar to the bar W, theirrelative position being such that in the normal position of the barsdescribed the brush R on the shaft Q is suspended horizontally. By meansof the lever on the brush B may be raised clear off the ground, or suchpressure downward as may be required can be directed against the brush Rby simply adjusting the lever a. This lever, it will be observed, passesthrough the bracket e, and is held by means of a pin fi'which may beplaced in any of the holes made in the bracket 6. The pivoted bar Wpasses through the bracket g, in which bracket a series of holes ismade.

Should it be desired to hold the light end of the brush R stationarywhile its opposite end is being raised or lowered, we place the pin h inone of the holes in the bracket 9, so that the lever a may be moved inthe required direction without adjusting the light end of the brush. Inthis way the brush B.

' bracket supported as described, so that it has a free flexiblemovement both vertically and horizontally and at its other end by whatis, in fact, a universal joint, the said brush has a perfectly-freemovement to adjust itself to any unevenness in the road without in anyway interfering with the driving mechanism by which the brush R isrevolved.

On reference to Figs. 2 and 4 it will be observed that the bristles ofthe brush R are fixed to strips or bars m, fitted at one end into therecessed disk 71 and at the other against the disk 19, both of whichdisks are securely fastened to the shaft Q. These strips or bars m areheld together by the bands g, which are cramped around the strips orbars, so-as to securely hold them together.

From this description it will be seen that we haveproducedasubstantially constructed street-sweeper which can be easilymanipulated, and in which all its Workin g parts may be readily got at.

What we claim as our invention is- 1. The bar D, pivoted at one end onthe axle E and having fixed to its other end a journal-box F, in which aspindle extending from the yoke G is journaled, in combination with thebracket H, pivotally connected to the yoke G and having a journal-boxformed in it to receive the shaft Q.

2. The bevel-pinion P, fixed to the shaft Q, journaled in the bracket H,and the bevelpinion 0, carried by a spindle extending from the bracketH, in combination with the sprocket-wheel L, sprocket-chain N, andsprocketwheel 0, arranged substantially as and for the purposespecified.

3. The bar D, pivoted at one end on the axle E and having fixed to itsother end a journal-box F, in which a spindle extending from the yoke Gis journaled, and the bracket H,pivota11y connected to the yoke Gandhaving a journal-box formed in it to receive the shaft Q, incombinationwith the bevel-pinion T, fixed to the shaft Q, journaled inthe bracket H, the bevel-pinion 0, carried by a spindle extending fromthe bracket H, a sprocketwheel L, sprocket-chain N, and sprocketwheel 0,arranged substantially as and for the purpose specified.

4. A rotating brush-shaft Q, suitably supported at one end, a rod J,connected at one end to a properly-supported pivoted bar Y and at itsother end to the bracket H, which supports the other or driven end ofsaid shaft Q, in combination with yoke G, pivotallyconnected to thebracketH and journaled on the rod D, substantially as described. I

5. The rod V, arranged to connect the socket S, in which the light endof the shaft Q is supported, to the pivoted bar W, in combination withthe equalizing-bar Z, suspended from the pivoted lever a and connected,respectively, to the pivoted bar W and the pivoted bar Y in such amanner that the weight supported by the said pivoted bars shall beequally divided betweenthe ends of the said equalizing-bar Z, arrangedsubstantially as and for the purpose specified.

6. A cylindrical brush made in segments supported by and between two endpieces fixed to the shaft Q and held together and in position byadjustable metal bands, arranged substantially as and for the purposespecified.
